Abstract: An electronic vent valve for an electronically controlled pneumatic (ECP") braking system having a plurality of braking sites at which a braking force can be applied. The ECP braking system includes a master controller processing circuit, individual braking control units located proximate each of the braking sites and a brake pipe supplying compressed air to the braking sites. The electronic vent valve is in fluid communication with the compressed air carried by the brake pipe and has an open position for substantially venting the compressed air from the brake pipe and a closed position for substantially retaining the compressed air within the brake pipe. The electronic vent valve includes a control circuit for causing the valve to open during emergency braking operations, thereby assuring a rapid decrease in the brake pipe pressure.      The control circuit preferably includes a brake pipe pressure sensor and a microprocessor for calculating a rate of change of the brake pipe pressure (dP/dt) and for causing the valve to open whenever the calculated rate of change of brake pipe pressure exceeds a threshold value. The control circuit can additionally cause the valve to open in response to a direct command from the master controller and can transmit to the master controller various operational characteristics of the braking system and the microprocessor itself.

Abstract: An anchoring device for anchoring an oil well tubing string within an oil well casing. The device generally comprises a drive mandrel and an anchor mandrel. The drive mandrel has an upper end and a lower end, with the upper end releasably securable to an oil well tubing string. The anchor mandrel has an upper end that is releasably securable to the drive mandrel. The anchor mandrel is selectively engagable and disengagable with the interior surface of an oil well casing through the use of a plurality of rotatable slips. The slips have a gripping surface to contact and adhere to the interior surface of the oil well casing such that when the anchor mandrel is rotated in a first direction the slips are rotatably deployed to an engaged position with the gripping surfaces in contact with the interior surface of the oil well casing. Rotation of the anchor mandrel in a second opposite direction causes the slips to be rotatably retracted from their engaged position to a disengaged position such that the gripping surfaces are withdrawn from contact with the interior surface of the oil well casing. A shear mechanism may be employed between the drive and anchor mandrels to alow for controled separation of the mandrels under pre-determined tensile loading.

Granted: 2008-12-23
Abstract: Simultaneous slicing and washing of relatively firm raw vegetable or fruit products is accomplished in a vat of water into which a slicer apparatus is positioned such that the slices are formed and discharge directly into the water An inclined takeout conveyor serves to receive the slices and remove them from the water. A circulating water current and fluid jets urge the slices to disperse onto the conveyor. A spray of water or air blast removes residual vegetable matter from the slice surfaces before leaving the takeout conveyor for further processing. Slicing and washing a vegetable in a flume volute where the slices are dispersed onto a takeout conveyor is disclosed where the water medium is collected in a tub and recycled back to flow in the flume to a level that covers the slicer's operative parts. The apparatus may be used for simultaneous slicing and cooking of raw vegetables where hot cooking oil is maintained in the system and recycled for reheating.

Abstract: Apparatus and method for manufacturing helically wound insulated conductors with filament fillers includes first and second payoff stations for paying off a plurality of insulated conductors and elongate filaments of filler materials. These cable components are guided from the payoff stations to a closing die, and are arranged in positions suitable for twisting into a cable by a double twist machine to form a cable of twisted insulated components forming radially outwardly facing helical interstices each of which is substantially filled with another one of the filaments of filler material. Differential or incremental lengths of filler material are metered upstream of the double twist machine to compensate for the differences in the radial distances of the insulated conductors and filaments of filler material on the center or cable of the axis. In this way, the helical interstices are more fully filled and the resulting cable has an exterior surface with minimal voids so that covering of the resulting cable with an outer elastomeric jacket or coating results in a substantially smoother and aesthetically pleasing cable with minimal surface irregularities.
